I've been concerned for several year over the sharp decline of native bees, so any research, mapping etc may be of great help.
"We know that bee populations are declining worldwide, and to understand the reasons for that, we need to conduct regional-scale studies, such as this, that might help explain the specific causes," LeCroy said.
The article is interesting while describing how, in the 70's we brought over some Asian bees and a second Asiatic variety appeared but exactly how, no one knows! While they are boosting our numbers they are causing a further drop in native bees.
I don't care about honey for myself. It's pollination that is so crucial.
Bees are critical for the sustenance of our food supplies. Anything that reduces the bee population substantially could prove to be disastrous to our agricultural industries.
